Pledge of Allegiance

Also called the “Pledge to the Flag.” The American patriotic vow, which is often recited at formal government ceremonies, including Independence Day ceremonies for new citizens: “I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation under God, indivisible, with liberty and justice for all.”

Note

The phrase under God, added in 1954 (more than sixty years after the pledge was originally published), has inspired heated debate over the separation of church and state.
